Brass Manometric Reduction Nipple, Type RDN
The internal and external threaded nipple made of high-quality brass is designed in compliance with EN 837-1, ensuring a reliable and precise connection for pressure gauges and related equipment. Its construction enables the installation of a pressure gauge into a larger socket, with the gauge mounted securely to the internal thread d1. The innovative self-sealing system, based on the conical design at the bottom of the d1 bore, guarantees tightness by pressing into the centering plug of the gauge connection. Both d1 and d2 threads are additionally protected against loosening with a special adhesive, providing long-term stability and safety of use. This robust connector is suitable for non-aggressive liquids and gases, making it an excellent choice for pressure gauges, taps, valves, and other compatible accessories. Durable, precise, and easy to install, it ensures dependable performance in a wide range of industrial and technical applications.
